ABSTRACT

A method including determining, by a device, an assigned key pair including an assigned public key and an assigned private key; determining, by the device for a group associated with a folder, a group access key pair including a group access public key and a group access private key; encrypting, by the device, the group access private key by utilizing the assigned public key; and accessing, by the device, the folder based at least in part on decrypting the group access private key. Various other aspects are contemplated.

FIELD OF DISCLOSURE

Aspects of the present disclosure generally relate to use of computer hardware and/or software to manage data, and in particular to grouping data in an organized storage system.

BACKGROUND

Various methods of cryptography (e.g., encrypting and decrypting data) are known. Encryption may be associated with changing the data from being in a transparently readable format to being in an encoded, unreadable format with the help of an encryption algorithm. Decryption may be associated with changing the data from being in the encoded, unreadable format to being in the transparently readable format with the help of a decryption algorithm. Encoded/encrypted data may be decoded/decrypted with a given decryption key. In an example, symmetric cryptography may utilize encryption and decryption algorithms that rely on a single private key for encryption and decryption of data. Symmetric cryptography is considered to be relatively speedy. One example of an encryption and decryption algorithm utilized by symmetric encryption may be an AES encryption cipher. On the other hand, asymmetric cryptography may utilize encryption and decryption algorithms that rely on two separate but mathematically-related keys for encryption and decryption of data. For instance, data encrypted using a public key may be decrypted using a separate but mathematically-related private key. The public key may be publicly available through a directory, while the private key may remain confidential and accessible by only an owner of the private key. Asymmetric encryption may also be referred to as public key cryptography. One example of an encryption and decryption algorithm utilized by asymmetric encryption may be Rivest-Shamir-Adleman (RSA) protocol.

FIG. 1 is an illustration of an example system 100 associated with grouping data in an organized storage system, according to various aspects of the present disclosure. The system 100 includes one or more user devices 102 communicating a stateless infrastructure 110 including a processing unit 112 and a database (e.g., memory) 114. In an example, a user device 102 may include a processing unit 106 and may utilize an installed client application 104 to communicate with an application programming interface (API) (not shown) included in the stateless infrastructure 110. In some aspects, the user device 102 and the stateless infrastructure 110 may communicate with one another over a network 120. The network 120 may be wired or wireless network. In some aspects, the network 120 may include one or more of, for example, a phone line, a local-area network (LAN), a wide-area network (WAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork. In some aspects, the network 120 may include a digital telecommunication network that permits several nodes to share and access resources.

The user device 102 may be a physical computing device capable of hosting a client application and of connecting to the network 120. The user device 102 may be, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the user device 102 may include, for example, Internet-of-Things (IoT) devices such as VSP smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. The user device 102 may include and/or may be associated with a communication interface to communicate (e.g., receive and/or transmit) data.

In some aspects, the stateless infrastructure 110 may provide the user device 102 with a client application 104 to be installed on the user device 102. The client application 104 may enable a processor (e.g., processing unit 106, processor 520) associated with the user device 102 to encrypt and decrypt the data. In some aspects, the client application 104 and/or the stateless infrastructure 110 may utilize one or more encryption and decryption algorithms to encrypt and decrypt the data. The encryption algorithms and decryption algorithms may employ standards such as, for example, data encryption standards (DES), advanced encryption standards (AES), Rivest-Shamir-Adleman (RSA) encryption standard, Open PGP standards, file encryption overview, disk encryption overview, email encryption overview, etc. Some examples of encryption algorithms include a triple data encryption standard (DES) algorithm, Rivest-Shamir-Adleman (RSA) encryption algorithm, advanced encryption standards (AES) algorithms, Twofish encryption algorithms, Blowfish encryption algorithms, IDEA encryption algorithms, MD5 encryption algorithms, HMAC encryption algorithms, etc.

In some aspects, data may include any information such as private information including, for example, bank account numbers, credit card numbers, various passwords, etc. In some aspects, the data may include electronic information included in files such as, for example, photographs, documents, compact discs (CDs), digital video disks (DVDs), etc. including written, printed, and/or electronic matter that provides information and/or evidence.

The stateless infrastructure 110 may include the processing unit 112 and the database 114. The processing unit 112 may include a logical component configured to perform complex operations to evaluate various factors associated with encrypting and decrypting the data. The database 114 may store various pieces of information associated with encrypting and decrypting the data, including encrypted content and/or encrypted key information. In some aspects, the stateless infrastructure 110 may include an application programming interface (API) (not shown) to communicate with the client application 104. The stateless infrastructure 110 may include or be associated with a communication interface to communicate (e.g., transmit and/or receive) data.

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

A user device may request data storage services from a data storage service provider (DSSP). Such data storage services may include cloud storage services that enable the user device to utilize, for example, the Internet to store data on remote servers and/or storage devices managed by the DSSP. The data storage services may also be referred to as cloud backup services, online data storage services, online drive storages, file hosting services, file storage services, or the like. The DSSP may attempt to protect the stored data by requiring the user device to provide credentials (e.g., username, password, one-time passwords, one-time tokens, or the like) to gain authorized access to the stored data. The data storage services may be available via use of a web interface and/or an application interface.

In some instances, the DSSP may fail to protect the stored data. In an example, a third party may gain unauthorized access to the stored data by, for example, hacking into the servers and/or storage devices managed by the DSSP. In another example, internal devices associated with the DSSP that have access to the servers and/or storage devices managed by the DSSP may gain unauthorized access to the stored data. As a result, an integrity associated with the stored data may be compromised. To regain access to the stored data and/or to protect the stored data, the user device and/or the DSSP may expend resources (e.g., management resources, memory resources, computational/processing resources, power consumption resources, system bandwidth, network resources, etc.) that may otherwise be used for more suitable tasks associated with the data storage services.

Various aspects of systems and techniques discussed in the present disclosure are associated with encrypting and data. In some aspects, a DSSP may provide a stateless system including a stateless infrastructure and/or a client application installed on a user device. In some aspects, the stateless infrastructure may provide the user device with the client application. In some aspects, the client application may enable the user device to encrypt and decrypt the data that the user device may wish to protect. In an example, the client application may enable the user device to encrypt data, to store the encrypted data, and to decrypt the encrypted data. In some aspects, the user device may encrypt the data, store the encrypted data, and decrypt the encrypted data without the stateless infrastructure having access to and/or storing unencrypted data. As a result, even if a third party gains unauthorized access to the client application and/or the stateless infrastructure, the unauthorized access may lead to encrypted data, which the third party may not be able to decrypt. The client application and/or the stateless infrastructure may employ a particular arrangement of keys to encrypt and decrypt the data. Such particular arrangement of keys may be critical because it enables the client application and/or the stateless infrastructure to provide data storage services (e.g., protect stored data) without storing unencrypted data. In this way, the client application and/or the stateless infrastructure may mitigate instances of the data becoming compromised, thereby enabling efficient utilization of resources (e.g., management resources, memory resources, computational/processing resources, power consumption resources, system bandwidth, network resources, etc.) associated with the user device and/or the stateless infrastructure for more suitable tasks related to the data storage services.

Additional aspects of systems and techniques discussed herein enable the stateless system to provide virtual groups and may enable authorized access to the virtual groups and prevent unauthorized access to the virtual groups. A virtual group may be associated with a plurality of registered accounts. Further, the virtual group may include and/or be associated with a plurality of folders (e.g., virtual folders) that include and/or are associated with encrypted content. In some aspects, as discussed below in further detail, the stateless system may provide one or more relationships using a particular key arrangement. Such particular key arrangement may be critical because it enables authorized access by user devices associated with the plurality of registered accounts to the folders and/or the encrypted content, and prevents unauthorized access to the folders and/or the encrypted content, without the stateless infrastructure having access to unencrypted data.

In some aspects, the client application and/or the stateless infrastructure may determine an assigned key pair including an assigned public key and an assigned private key; determine, for a group associated with a folder, a group access key pair including a group access public key and a group access private key; encrypt the group access private key by utilizing the assigned public key; and access the folder based at least in part on decrypting the group access private key.

FIG. 2 is an illustration of an example flow 200 associated with grouping data in an organized storage system, according to various aspects of the present disclosure. The example flow 200 may include a user device 102 in communication with a stateless infrastructure 110. In some aspects, the user device 102 may install a client application 104 associated with the stateless infrastructure 110 and may use the client application 104 to communicate with an application programming interface (API) and a processor (e.g., processing unit 112, processor 1220) associated with the stateless infrastructure 110. In some aspects, the user device 102 and the stateless infrastructure may communicate over a network (e.g., network 120).

As shown by reference numeral 210, the user device 102 may register an account with the stateless infrastructure 110. In some aspects, during the registration, the user device 102 may provide registration information such as, for example, identity of an owner of the user device 102, a phone number associated with the user device 102, an email address associated with the user device 102, or the like. In some aspects, the user device 102 may set up an access system including, for example, username, password, or the like to subsequently gain access to the registered account.

In some aspects, the stateless infrastructure 110 may provide the client application 104 to be installed on the user device 102. The client application 104 may enable the user device 102 to receive information to be processed by the client application 104 and/or by the stateless infrastructure 110. The client application 104 may include a graphical interface to receive the information via a local input interface (e.g., touch screen, keyboard, mouse, pointer, etc.) associated with the user device 102. The information may be received via text input or via a selection from among a plurality of options (e.g., pull down menu, etc.). In some aspects, the client application 104 may activate and/or enable, at a time associated with the registration (e.g., after the registration), the graphical interface for receiving the information. For instance, the client application 104 may cause a screen (e.g., local screen) associated with the user device 102 to display, for example, a pop-up message to request entry of the information. Further, the client application 104 may enable transmission of at least a portion of the information to the stateless infrastructure 110.

As shown by reference numeral 220, the stateless system may determine information based at least in part on the registration of the account with the stateless infrastructure 110. In an example, the client application 104 may determine an asymmetric assigned key pair for the registered account associated with user device 102. The assigned key pair may be unique to the registered account and may include an assigned public key and an assigned private key. In this way, the assigned public key and the assigned private key may be account-specific and/or maybe associated with the registered account. In some aspects, the assigned public key and the assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the assigned public key may be decrypted by utilizing the assigned private key.

Further, the client application 104 may receive a master string of alphanumeric characters from the user device 102. In some aspects, the master string may be unique and be associated with the registered account associated with the user device 102. Based at least in part on receiving the master string, the client application 104 may determine a master key. In some aspects, the client application 104 may utilize a password derivation function and/or a key derivation function to determine the master key based at least in part on the master string. The password derivation function and/or the key derivation function may perform password hashing to determine the master key. The client application 104 may utilize the master key to encrypt the assigned private key associated with the registered account.

As shown by reference numeral 230, the client application 104 may transmit, and the stateless infrastructure 110 may receive, at least a portion of the information determined by the client application 104. For instance, the client application 104 may transmit, for example, the assigned public key and the encrypted assigned private key to the stateless infrastructure 110. The stateless infrastructure 110 may store and correlate the received information in association with the registered account associated with the user device 102. In some aspects, when another device associated with the registered account (e.g., another device owned by and/or available to the owner of the user device 102) wishes to decrypt the encrypted content, the stateless infrastructure 110 may provide such information to the other device.

In some aspects, the stateless system may provide one or more folders. In an example, the client application 104 may enable the user device 102 to associate (e.g., store) the one or more folders locally and/or remotely. In an example, the user device 102 may provide the one or more folders in association with a local memory and/or a remote memory associated with the user device 102. In another example, the user device 102 may provide the one or more folders in association with a database (e.g., database 114) associated with data storage services provided by the stateless system. In yet another example, the user device 102 may provide the one or more folders in association with a hand-held memory (e.g., a USB thumb drive, flash drive, etc.). In some aspects, the user device 102 may provide a folder based at least in part on storing, in a memory, data (e.g., information, encrypted content, etc.) within and/or in association with the folder. In some aspects, the one or more folders may include one or more virtual folders. A virtual folder may include, for example, a pointer to indicate a location of the data and/or information (e.g., a “shortcut”) indicating a path to the location of the data.

For a given virtual folder, as shown by reference numeral 240, the client application 104 may determine a folder access key pair. The folder access key pair may include a folder access public key and a folder access private key. The folder access public key and the folder access private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the folder access public key may be decrypted by utilizing the folder access private key. Further, the client application 104 may encrypt the folder access private key by utilizing the assigned public key associated with the registered account.

As shown by reference numeral 250, the client application 104 may transmit, and the stateless infrastructure 110 may receive, at least a portion of the information determined by the client application 104. For instance, the client application 104 may transmit the folder access public key and the encrypted folder access private key to the stateless infrastructure 110. In some aspects, when another device associated with the registered account (e.g., another device owned by and/or available to the owner of the user device 102) wishes to access the virtual folder, the stateless infrastructure 110 may provide such information to the other device.

When the user device 102 (or the other device associated with the registered account) may wish to access the virtual folder, the user device 102 (e.g., or the other device) may access the registered account and request the encrypted assigned private key from the stateless infrastructure 110. Based at least in part on receiving the request, as shown by reference numeral 260, the stateless infrastructure 110 may transmit, and the client application 104 may receive, the encrypted assigned private key. In some aspects, as shown by reference numeral 270, the stateless infrastructure 110 may transmit additional information such as, for example, the encrypted folder access private key, the folder access public key, location of the virtual folder, etc. when the user device 102 and/or the other device may not have access to such additional information.

Based at least in part on receiving the encrypted assigned private key, the encrypted folder access private key, the folder access public key, etc., the client application 104 may be enabled to access the virtual folder. In an example, the client application 104 may request entry of the master string and based at least in part on receiving the master string, the client application 104 may determine the master key that was utilized to encrypt the assigned private key. The client application 104 may utilize the master key to decrypt the assigned private key. The client application 104 may utilize the assigned private key to decrypt the encrypted folder access private key based at least in part on an association between the assigned private key and the assigned public key. Further, the client application 104 may utilize the access private key to access the virtual folder. In some aspects, access to the folder may enable the client application 104 to access encrypted content associated with and/or included within the virtual folder.

In some aspects, one or more functionalities performed by the client application 104 may be included in and/or may be performed by the stateless infrastructure 110, and vice versa.

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2 .

FIG. 3 is an illustration of an example flow 300 associated with grouping data in an organized storage system, according to various aspects of the present disclosure. The example flow 300 may include a user device 102 in communication with a stateless infrastructure 110. In some aspects, the user device 102 may install a client application 104 associated with the stateless infrastructure 110 and may use the client application 104 to communicate with an application programming interface (API) and a processor (e.g., processing unit 112, processor 520) associated with the stateless infrastructure 110. In some aspects, the user device 102 and the stateless infrastructure may communicate over a network (e.g., network 120).

In some aspects, the user device 102 may wish to encrypt data and to store the encrypted data. As discussed below with respect to FIG. 4 , the user device 102 may wish to encrypt data and to store the encrypted data within and/or in association with a virtual folder. In some aspects, the client application 104 may determine respective symmetric keys and content access key pairs for each piece of data (e.g., content) that the user device 102 may wish to encrypt. In this way, the symmetric key and the content access key pair may be content-specific. Examples of content may include any information including, for example, alphanumeric data such as passwords, credit card numbers, bank account numbers, etc. and/or information that is written, printed, and/or electronically included in documents and/or files such as photographs, or processing documents, CDs, DVDs, etc.

For given content, as shown by reference numeral 310, the client application 104 may utilize a random bit generator to determine a symmetric key. In an example, the symmetric key may be a random key including a sequence of unpredictable and unbiased information. Further, the client application 104 may determine a content access key pair including a content access public key and a content access private key. The content access public key and the content access private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the content access public key may be decrypted by utilizing the content access private key.

The client application 104 may utilize the symmetric key and the content access key pair to encrypt the content. In an example, the client application 104 may encrypt the content access private key using the assigned public key associated with the registered account (e.g., first encryption of content access private key). The client application 104 may encrypt the symmetric key by utilizing the content access public key. The client application 104 may encrypt the content by utilizing the symmetric key. In some aspects, the client application 104 may enable the user device 102 to store the encrypted content.

As shown by reference numeral 320, the client application 104 may transmit, and the stateless infrastructure 110 may receive, at least a portion of the information determined by the client application 104. For instance, the client application 104 may transmit one or more of the content access public key, the encrypted content access private key, the encrypted symmetric key, or the encrypted data to the stateless infrastructure 110. In some aspects, when another device associated with the registered account (e.g., another device owned by and/or available to the owner of the user device 102) wishes to decrypt the encrypted content, the stateless infrastructure 110 may provide such information to the other device.

When the user device 102 (or the other device associated with the registered account) may wish to decrypt the encrypted content, the user device 102 (e.g., or the other device) may access the registered account and request the encrypted assigned private key (discussed with respect to FIG. 2 ). Based at least in part on receiving the request, as shown by reference numeral 330, the stateless infrastructure 110 may transmit, and the client application 104 may receive, the encrypted assigned private key. In some aspects, as shown by reference numeral 340, when the user device 102 and/or the other device may not have access to the encrypted content, the stateless infrastructure 110 may also transmit the first encrypted content access private key, the encrypted symmetric key, and the encrypted content to the user device 102 and/or the other device.

Based at least in part on receiving the encrypted assigned private key, the encrypted content access private key, the encrypted symmetric key, and/or the encrypted content, as shown by reference numeral 350, the client application 104 may decrypt the content. For instance, the client application 104 may request entry of the master string and based at least in part on receiving the master string, the client application 104 may determine the master key that was utilized to encrypt the assigned private key (discussed above with respect to FIG. 2 ). The client application 104 may utilize the master key to decrypt the assigned private key. The client application 104 may utilize the assigned private key to decrypt the encrypted content access private key based at least in part on an association between the assigned private key and the assigned public key. Further, the client application 104 may utilize the content access private key to decrypt the symmetric key based at least in part on an association between the access private key and the access public key. The client application 104 may utilize the symmetric key to decrypt the content. In this way, the user device 102 (and/or the other device) may directly access the content.

In some aspects, one or more functionalities performed by the client application 104 may be included in and/or may be performed by the stateless infrastructure 110, and vice versa.

As indicated above, FIG. 3 is provided as an example. Other examples may differ from what is described with regard to FIG. 3 .

FIG. 4 is an illustration of an example flow 400 associated with grouping data in an organized storage system, according to various aspects of the present disclosure. The example flow 400 may include a user device 102 in communication with a stateless infrastructure 110. In some aspects, the user device 102 may install a client application 104 associated with the stateless infrastructure 110 and may use the client application 104 to communicate with an application programming interface (API) and a processor (e.g., processing unit 112, processor 520) associated with the stateless infrastructure 110. In some aspects, the user device 102 and the stateless infrastructure may communicate over a network (e.g., network 120).

In some aspects, the user device 102 may wish to store encrypted content within and/or associate encrypted content with a virtual folder. In this case, the stateless system may enable provision of a relationship between the encrypted content and the virtual folder. In some aspects, the relationship may utilize a particular key arrangement. Such particular key arrangement may be critical because, without the stateless infrastructure having access to unencrypted data, the stateless system enables authorized access to the encrypted content via the virtual folder and prevents unauthorized access to the encrypted content via the folder.

To provide the relationship between given encrypted content and the virtual folder, as shown by reference numeral 410, the client application 104 may again encrypt the content access private key associated with the encrypted content by utilizing the folder access public key associated with the virtual folder (e.g., second encryption of content access private key).

As shown by reference numeral 420, the client application 104 may transmit the second encrypted content access private key to the stateless infrastructure 110. In some aspects, when another device associated with the registered account (e.g., another device owned by and/or available to the owner of the user device 102) wishes to decrypt the encrypted content via access to the virtual folder, the stateless infrastructure 110 may provide such information to the other device.

When the user device 102 (or the other device associated with the registered account) may wish to decrypt the encrypted content via access to the virtual folder, the user device 102 (e.g., or the other device) may access the registered account and request the encrypted assigned private key (discussed with respect to FIG. 2 ). Based at least in part on receiving the request, as shown by reference numeral 430, the stateless infrastructure 110 may transmit, and the client application 104 may receive, the encrypted assigned private key. In some aspects, as shown by reference numeral 440, when the user device 102 and/or the other device may not have access to the encrypted content, the stateless infrastructure 110 may also transmit the second encrypted content access private key, encrypted symmetric key, content access public key, and/or encrypted content to the user device 102 and/or to the other device.

Based at least in part on receiving the encrypted assigned private key, the second encrypted content access private key, the encrypted symmetric key, and/or the encrypted content, as shown by reference numeral 450, the client application 104 may decrypt the content via access to the virtual folder. For instance, the client application 104 may request entry of the master string and based at least in part on receiving the master string, the client application 104 may determine the master key that was utilized to encrypt the assigned private key (discussed above with respect to FIG. 2 ).

FIG. 5 is an illustration of an example flow 500 associated with grouping data in an organized storage system, according to various aspects of the present disclosure. The example flow 500 may include a user device 102 in communication with a stateless infrastructure 110. In some aspects, the user device 102 may install a client application 104 associated with the stateless infrastructure 110 and may use the client application 104 to communicate with an application programming interface (API) and a processor (e.g., processing unit 112, processor 1220) associated with the stateless infrastructure 110. In some aspects, the user device 102 and the stateless infrastructure may communicate over a network (e.g., network 120).

In some aspects, the stateless system may provide one or more groups. In an example, the client application 104 may enable the user device 102 to associate (e.g., store) the one or more groups locally and/or remotely. In an example, the user device 102 may provide the one or more groups in association with a local memory and/or a remote memory associated with the user device 102. In another example, the user device 102 may provide the one or more groups in association with a database (e.g., database 114) associated with data storage services provided by the stateless system. In yet another example, the user device 102 may provide the one or more groups in association with a hand-held memory (e.g., a USB thumb drive, flash drive, etc.). In some aspects, the user device 102 may provide a group based at least in part on storing, in a memory, data (e.g., information, encrypted content, etc.) within and/or in association with a folder (e.g., virtual folder). In some aspects, the one or more groups may include one or more virtual groups.

In some aspects, a virtual group may be associated with a plurality of registered accounts. Further, the virtual group may be associated with a plurality of folders including, for example, virtual folders. Based at least in part on being associated with (e.g., part of) the virtual group, user devices associated with the plurality of registered accounts may have authorized access to the plurality of folders and/or to encrypted contents included within and/or associated with the plurality of folders. To facilitate access to the plurality of folders, the virtual group may include, for example, a pointer to indicate a location of the data and/or information (e.g., a “shortcut”) indicating a path to the location of a folder.

For a given virtual group, as shown by reference numeral 510, the client application 104 may determine a group access key pair. The group access key pair may include a group access public key and a group access private key. The group access public key and the group access private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the group access public key may be decrypted by utilizing the group access private key. Further, the client application 104 may encrypt the group access private key by utilizing the assigned public key associated with a registered account associated with the user device 102.

As shown by reference numeral 520, the client application 104 may transmit, and the stateless infrastructure 110 may receive, at least a portion of the information determined by the client application 104. For instance, the client application 104 may transmit the group access public key and the encrypted group access private key to the stateless infrastructure 110. In some aspects, when another device associated with the registered account (e.g., another device owned by and/or available to the owner of the user device 102) wishes to access the virtual group, the stateless infrastructure 110 may provide such information to the other device.

When the user device 102 (or the other device associated with the registered account) wishes to access the virtual group, the user device 102 (e.g., or the other device) may access the registered account and request the encrypted assigned private key from the stateless infrastructure 110. Based at least in part on receiving the request, as shown by reference numeral 530, the stateless infrastructure 110 may transmit, and the client application 104 may receive, the encrypted assigned private key. In some aspects, as shown by reference numeral 540, the stateless infrastructure 110 may transmit additional information such as, for example, the encrypted group access private key, group access public key, location of the virtual group, etc. when the user device 102 and/or the other device may not have access to such additional information.

Based at least in part on receiving the encrypted assigned private key, the encrypted group access private key, group access public key, etc., as shown by reference numeral 550, the client application 104 may access the virtual group. In an example, the client application 104 may request entry of the master string associated with the registered account and based at least in part on receiving the master string, the client application 104 may determine the master key that was utilized to encrypt the assigned private key. The client application 104 may utilize the master key to decrypt the assigned private key. The client application 104 may utilize the assigned private key to decrypt the encrypted group access private key. In some aspects, the client application 104 may utilize the association between the assigned private key and the assigned public key to decrypt the encrypted group access private key. Further, the client application 104 may utilize the group access private key to access the virtual group. In some aspects, access to the virtual group may enable the client application 104 to access the plurality of folders associated with and/or included within the virtual group and/or to the encrypted content associated with and/or included within the plurality of folders.

In some aspects, one or more functionalities performed by the client application 104 may be included in and/or may be performed by the stateless infrastructure 110, and vice versa.

In some aspects, the user device 102 and the stateless infrastructure may communicate over a network (e.g., network 120).

In some aspects, the registered account associated with the user device 102 may be associated with, for example, a virtual group. Further, the user device 102 may wish to associate a plurality of folders with the virtual group. In this case, the stateless system may enable provision of a relationship between each of the plurality of folders and the virtual group. In some aspects, the relationship may utilize a particular key arrangement. Such particular key arrangement may be critical because, without having access to unencrypted data, the stateless system enables authorized access to the plurality of folders (and associated encrypted content) via the virtual group and prevents unauthorized access to the plurality of folders (and associated encrypted content).

To provide the relationship between a given folder and the virtual group, as shown by reference numeral 610, the client application 104 may encrypt the folder access private key associated with the folder by utilizing the group access public key associated with the virtual group. In some aspects, this relationship may associate the given folder with the virtual group, and a registered account having authorized access to the virtual group may have authorized access to the given folder (and associated encrypted content).

As shown by reference numeral 620, the client application 104 may transmit information including the encrypted folder access private key, the group access public key, etc. to the stateless infrastructure 110. In some aspects, when another device associated with the registered account (e.g., another device owned by and/or available to the owner of the user device 102) wishes to decrypt the encrypted content via access to the virtual group, the stateless infrastructure 110 may provide such information to the other device.

When the user device 102 (or the other device associated with the registered account) may wish to access the folder via the virtual group, the user device 102 may transmit a request to the stateless infrastructure 110 to provide the information to access the folder. Based at least in part on receiving the request, as shown by reference numeral 630, the stateless infrastructure 110 may transmit to the client application 104 information to access the folder, the information including the encrypted folder access private key, the group access public key, etc.

Based at least in part on receiving the information to access the folder, as shown by reference numeral 640, the client application 104 may access the folder via the virtual group. In some aspects, the client application 104 may utilize the group access private key to decrypt the encrypted folder access private key. In some aspects, the client application 104 may utilize the association between the group access private key and the group access public key to decrypt the encrypted folder access private key. The client application 104 may utilize the folder access private key to access the folder, as discussed above with respect to FIG. 2 . Further, based at least in part on accessing the folder, the client application 104 may decrypt the encrypted content included within and/or associated with the folder, as discussed above with respect to FIG. 4 .

In some aspects, one or more functionalities performed by the client application 104 may be included in and/or may be performed by the stateless infrastructure 110, and vice versa.
